SAFETY ATTACHMENT FOR GAS-COCKS.

SPECIFICATION forming part of Letters Patent No. 324,123, dated August 11, 1885.

Application filed Juno 21, 1884.

.To all whom it may concern: Y

Be it known that I, HEsTER LAUDE, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and Improved Safety Device for Gas-Cocks, of which the following is a specification. Y

The cocks of gas-burners after being in use a short time generally become so loose that unless care be exercised in closing them they are apt to be turned back, so as to allow the gas to escape after being extinguished.

Now, this invention has for its object to provide a simple and effective means for insuring the complete closing of gascocks and holding them in closed position, and giving audible notice at the time of such action; and it con sists in the application of a spring fixed to the body, and bearing against a disk on the end of the plug of the cock, the disk having notches into which catch projections on the spring when the gas is shut off, which offer sufcient frictional resistance to prevent the accidental turning vof the plug. The free ends of the spring, which extend some distance beyond the disk, are so constructed as to vibrate and emit a sound as they come in contact, which they do when the projections fall into the notches of the disk, thus clearly indicating that the cock is properly closed. To insure the sharp quick action of the spring to cause it to produce a clear distinct sound, the disk is fitted on the plug with a certain amount of rotary freedom, so that it is pushed forward when the projections of the spring pass over the edges of the notches, thus allowing the spring to react quickly, even though the plug be turned very slowly in shutting off the gas; but to describe my invention in'ore particularly, I will now refer to the accompanying drawings, in whichl Figure l is a plan view of a gas burner and cock provided with my safety device. Fig. 2 is a longitudinal section of the same. Fig. 3 is a view similar to Fig. l, showing a modification in the same.

In applying my new safety device to gascocks no material changes are made in the construction of the body c and plug b of the same. rIhe washer c has a flange, c', which bears on the top of the body a, audit is fitted on the end of the plug b, so as to turn with it-that (No model.)

is, by the formation of a flat on the side of the stud on which it rits-and is held in place by the screw d, in the ordinary manner. On the outside of the washer c, which is also flat on one side, is fitted the disk e, between the ange c' and the head of the screw d. This disk e is free to partly rotate on the washer c, but is moved around with it when the plug is turned.

The locking and sonorous spring f is held at its central part in the lug g, attached to or forming a part of the body a. It is bent, as shown, with the projections ff arranged to embrace the disk e, and with its two ends f 2 f 2 close together when the projections f f are in the notches e c of the disk e, as'shown in Fig. 1, in which the plug b is represented closed, and the screw d is removed to more clearly show the disk e.- When in this position the spring, by the projections f f being in the notches e of the disk e, offers sufficient resistance to prevent any accidental turning of the plug b; but the projections f f ride up the sides ofthe notches onto the periphery of the disk e when the gas is turned on, and separate the ends f 2 f 2 of the spring, as shown by the dotted lines. The sides of the notches are so inclined as to allow of the movement of the plug b in either direction.

Now, in turning the plug b so as to shut off the gas-say, in the direction indicated by the arrow-the edges e2 e2 of the notches of disk c come under the projections f f of the spring just after the gasway is fully closed, and these projections tlirowthe disk forward, as shown by the space between the flat in the disk and that on the washer, which allows the spring to react quickly, so that its two ends f2 f2 are brought sharply together and produce a clear and distinct sound.

It is evident the notched disk e may be con- I do not wish to confine myself to the particular construction shown; but,

Vhat I claim, and desire to secure by Letters Patent, is-- 1. The combination, with the body and plug IOO of a gasburner, of a notched disk carried by er c so as to partly rotate thereon, and the' the plug, and a spring secured at one end to spring f, secured to the body a and actuated the body, operated by the notched disk and by the disk e, substantially as and for the pur- 15 extending some distance beyond the same, snbpose set forth.
